Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
151 words
A METHOD FOR CO-REACTING A PLURALITY OF MOLTEN ELEMENTAL METALS TO FORM AN INTERMETALLIC COMPOUND OF SAID METALS WHILE MINIMIZING TEMPERATURE RISE OF THE REACTION MASS BECAUSE OF HEAT OF REACTION, WHICH COMPRISES GRADUALLY ADDING PORTIONS OF EACH OF SAID METALS AS SEPARATE SOLIDS TO THE SURFACE OF AN INITIALLY SHALLOW MOLTEN POOL OF SAID METALS AT SUBSTANTIALLY THE SAME AREA OF THE SURFACE OF SAID POOL SAID MOLTEN METALS IN SAID POOL BEING IN THE STOICHIOMETRIC PROPORTIONS FOR FORMATION OF THE DESIRED INTERMETALLIC COMPOUND, EACH OF THE METALS BEING ADDED AT RELATIVE RATES SUCH THAT THE RELATIVE PROPORTIONS OF SAID METAL ARE MAINTAINED IN SUBSTANTIALLY STOICHIOMETRIC PROPORTIONS FOR FORMATION OF SAID INTERMETALLIC COMPOUND, THE RATES OF ADDITION OF SAID METALS BEING MAINTAINED WITHIN RANGE SUCH THAT ALL MELTING OF THE ADDED METALS OCCURS SUBSTANTIALLY AT THE SURFACE OF SAID POOL, SAID CO-REACTING PROCEEDING DURING SAID GRADUAL ADDING OF SAID PORTIONS.
